MACHINE FOR FORMING HEEL-STIFFENERS.

SPECIFICATION forming part of Letters Patent No. 469,774, dated March 1, 1892.

Application filed August 15, 1891.

Serial No. 402,708. (No model.

To all whom it may concern: Be it known that I, LOUIS COTE, of St. Hyacinthe, in the Province of Quebec and Domiuion of Canada, have invented certain new and useful Improvements in Machines for Forming Heel-Stiffeners, of which the followin g, taken in connection with the accompanying drawings, is a specification.

My invention relates to machines for formin g heel-stiffeners and is an improvement upon the invention described in the Letters Patent No. 447,944, granted to me March 10, 1891; and it consists in certain novel features of construction, arrangement, and combination of parts which will be readily understood by reference to the description of the drawings and to the claims hereinafter given, and in which my invention is clearly pointed out.

Figure 1 of the drawings is a front elevation of so much of a machine as is necessary to illustrate my invention. Fig. 2 is a side Fig. 3 is a plan of the divided former, the molds and the table for supporting the same detached from the other parts of the machine. Fig. tis a vertical section on line 2 2 on Fig. 3. Fig. 5 is a vertical section on line 3 3 on Fig. 3. Fig. 6 is a horizontal sectionon line 4 4 on Fig. at. Fig. 7 is a horizontal section on line 5 5 on Fig. 4:. Fig. 8 is a partial horizontal section on line 6 6 on Fig. 2. Fig. 9 is a transverse vertical section through one of the side molds on line 7 7 on Fig. 7. Fig. lOisapartial vertical section on line 8 8 on Fig. 5. Fig.11 is asection of the spheroidal former and its shaft on line 9 9 on Fig. 8. Fig. 12 is a section of said former on line 0c 00 on Fig. 11. Fig. 13 is an elevation of the oamfor operating the former.

Fig. 14 is a sectional plan, the cutting plane being on line 10 10 on Fig. 13; and Fig. 15 is a section on line 11 11 on Fig. 14.

In the drawings, A is the main frame of the head of the machine'supported upon the column B, onlyasmall portion of which is shown said frame having mounted in suitable bearings thereon the and F.

G and G are the tight and loose pulleys on the shaft 0. 1

a, b, c, and d are spur gear-wheels connecting saidshafts; e and f, the fluted rolls for corrugatin g that portion of the counter-blank horizontal shafts O, D, E,

from which the flange or heel seat of the stifiener is to be formed, said rolls being connected together by the spur gears g and h, and have motion imparted thereto by the miter gear-Wheels t' and j.

H and H are respectively the former and mold for performing the second operation upon the blank and of imparting thereto curves both longitudinally and transversely.

I and I are respectively a revoluble disk and an adjustable mold for performing the third operation or the reshapingof the center or rear portion of the partially-formed or clam-shell counter-stiffener.

J is the table for supporting the molds and former for reshaping the sides of the stiffener, firmly bolted to the column B and having mounted in pendent bearings thereon the horizontally-reciprocatin g rod T, to which motion is imparted by the crank-pin 76, set in the crank-disk K, secured on a short shaft is, mounted in a bearing in the hub J, projecting horizontally from the foot or flange J 2 of said table J, said shaft having secured upon its other end the gear-wheeld, which engages with and has motion imparted thereto from the gear-wheel d. The rod T is provided with the notch Z in its under side, with which the latch-lever q engages to lock said rod to the bracket or arm R, fitted to said'rod and to a bearing in the slot 71. in the table J, and carrying at its upper end the flange-turner S.

So far the several parts are constructed," arranged, and operate substantially as deobjectionable on account of the time lost in making the change. To obviate this objection I mount in bearings in the frame A the sleeve-shaft E, having formed therein a bearing for the shaft E, so constructed and the shaft E so fitted thereto that said shaft E and the sleeve E must revolve together, and at the same time the shaft Emay be adjustable endwise in its bearing in said sleeve to vary the position of the spheroidal former relative to its socket. In the machine illustrated I have accomplished this by making a portion of the inner end of the shaft E square, as shown at E and forming a portion of the boreof the sleeve E of a corresponding shape andr se curing the shaft E in the desired positioli in said sleeve by meansof the set-screw m, which passes through the hub of thegear 0, fast on the sleeve E, and through said sleeve, as shown in Fig. 8. The left or outer end of the shaft E has formed thereon a head e, which fits into a counterbore in the former H, and the shaft has set in its side, a short distance to the right of said head, the stud 6 The former H has a hole through itto fit the shaft E at its headed end, and has formed in its inner wall the L-shaped groove a as seen in Fig. 12, into which the stud e enters as the former is moved toward the head e, and locks it in position when said former is turned, so as to bring the stud (2 into the circumferential portion of said groove. By this construction of the shaft E, sleeve E, and former- H the former and mold H can be very readily and easily removed and replaced by simply turning out the set-screw H and pushing back the mold H. to the position shown in. Fig. 8, turning the former on the shaft-E until the stud e is inline with the longitudinal portion of the groove a then, loosening the set-screw m, when the shaft E may be withdrawn from its sleeve and from the former, and then the mold H can be readily removed from its, socket H portant feature ofi .my invention and is of great. advantage.

The side-shaping molds O O are mounted.

upon studs 1n, set in the pistonsN, which pistons are pressed, toward each other by the rubber springs Q Q, substantially as shown and.

described in my before-cited prior patent. In

my present invention, however, the tensions of thespri'ngs Q Q areadjnsted by means of the tension-bolt n, which passes through the centers of the pistons N,the springs Q, and the. followers N N, and is provided with the wheel-nut N asshown in Fig. 4.

Theinner ends of the pistons N are beveled to form a suitable surface for the stop-wedge N toengage with tolimit the inward movement. of said pistons, said wedge being constructed and arranged to be forced, inward. to

said. pistons by the action thereon of the eccentricO, as shown in Figs. 5 and 6.

.The inner ends of the molds O 0 have mountedltherein the-forked studs '22. n, each carnyingin: its forked end an anti-friction roll niagainstwhich a, suitable surface onthe outer sides of the two parts. of the divided former P near their inner ends bears, said rolls.and studs being adjustable toward and fromsaid formers by means of the set-screws n as shown. in Figs. 3, 4, and 7. The roll n This is an imis kept in contact with the former by the tension of the spring 0, mounted npon the curved rod 0, fixed at one end in a hole in said mold O and resting at its other end in an open slot in the movable end of the plate 0 the slotted end of which is turned at right angles to its main body, and the opposite end of which is pivoted to the plate 0 secured to the piston N, the spring 0 being compressed A between the shoulder 0 of the mold O and the upturned slotted portion of the plate 0 and the rod 0 being provided in its outer end with the pin 0 to serve as a stop to limit the inward movement of the inner end of the mold, all as shown in Figs. 1, 3, and 7.

. In my prior patent the molds 0 were provided with lips to project under the formerto turn the side portions of the flange or heelseat of the stiifener, and a notched reciprocatin g plate was used to turn the central portion of said flange or heel-seat, and in order to allow the requisite motion to be given to said plate when the molds were clamping the stitfener between them and the former a portion of the lip on each mold had to be cut away. This was found to be objectionable on account of the said lips being thus made too short, so that they did not turn the side'portions of the flange sufficiently near to the heel end of the former. This objection is obviated in my present invention by pivoting to the under side of each of said molds 0- the segmental plate 19, fitted to fill or partially fill the space formed by cutting away the lip a, said plate being normally held in the position shown in Fig. 7 by the tension of the spring p, thus forming an extension of they shortened lip 6 and at the same time said plate is movable about its pivot p by the forward or inward movement of the notched flange-turning plate S, and limited in its outward movement by the stop-pin 19 coming in contact with the end of the-slot 19 as shown in Fig. 7.

In my prior patent the flange-turnin g plate S was secured in a fixed position on the arm R, which was fitted to bereciprocated in: the slot h by the rod T, to which it was connected by the latch-lever g, which waslocated above said rod T and was moved into engagement with the notch Z by means of a treadleon the door, and was disengaged by a spring, said rod T being provided with a verticalslot, into which projected a crank-pinby whichsaid rod 5 and flange-tn rner were reciprocated. a, greater or less distancefrom. the. centers. of

In my present invention the notchedfiangeturning plate S has its under side slightly inclined and roughened or serrated, andhasin- 1 serted beneath itthe correspondingly-tapered plate S, the uppersurface of which is also jroughened or serrated, said. plates. S and S being secured to the upper end of the arm. R

by the bolts 0' r, said plates being slotted, so

that it may be adjusted endwise bencaththe plate S in suchamanner as to=raise or lower said plate S to adapt it toditterent thicknesses of stock.

The latch-lever q, instead of being placed above the rod T, is placed below it and has adjustably pivoted and clamped to its movable end the segmental arm g which the operator touches with his knee to cause said lever to engage the notch Z in the rod T, the force of gravity disengaging said lever from said notch when the pressure of the knee is removed.

Instead of making the slot T vertical or at right angles to the axis of the rod T, as in my prior patent, I make it curved, with its central portion having a radius at its center line equal to the radius of the crank K, as shown in Fig. 5, whereby the rod T, when at the extreme of its outward movement, has a standstill or rest during nearly one-quarter of the revolution of-the crank K, during which time the latchlever (1 may be engagedwith or disengaged from the notch Z-with certainty. The curved arm g clamped to the movable end of the latch-lever q, may be adjusted about its pivotal connection to said lever to raise or lower the under side thereof to adapt it to the height of the operators knee.

The former P is made in two halves, divided longitudinally, as described in said prior patent; but instead of the two parts being hinged together at a point somewhat removed from the heel end of the former, about which point the said two parts Vibrate, and having theirheel ends beveled on their inner faces to permit said vibration, as in my prior patent,I now form longitudinal recesses r in the inner faces of the two parts of the former P, in which I'secure by screws or rivets r the springs T the opposite end of each spring having formed therein an eye to fit on the stud s,

set in the table J, said springs serving to prevent any endwise movement of the former and at the same time permit the two parts thereof to vibrate about a point 24; the extreme heel end of the former, as represented by the semicylindrical rib or lip s on one part of the former, which fits into a correspondinglyshaped recess in the other part, as clearly shown in Figs. 3 and 7.

A stud t is set in the table J and projects upward therefrom between the two parts of the former P, and has fitted thereon the crossbar t and the wheel-nut t for the purpose of preventing the former from being lifted by the action of the lips e on the molds in turning the flange under said former. The inner ends of the two parts of the former P have mounted therein the anti-friction rolls u u in position to be acted upon by the cam U in forcing said inner ends outward or away from each other. The cam U is divided transversely of its axis of revolution into two parts, each part having formed in its inner face two rectangular recesses 12 v, the bottoms of which are inclined toward each other and separated from each other by the rib 0 as shown in Fig. 14. Two wedges w w are placed in said recesses between said two parts of the cam and are adjustable toward and from each other by the screw 1.0 having formed thereon two collars 20 near the middle of its length which embrace the slotted ribs '0 and having formed on one end thereof a right-h and screw-thread and on its other end a left-hand screw-thread, which threads fit correspondingly threaded holes in the wedges w to, so that by turning said screw the wedges may be moved toward or from each other and thus expand said cam U in the direction of the length of its axis to compensate for the wear of the operating-surface of said cam and the peripheries of the rolls to u, all as shown in Figs. 18, 14, and 15. s

V is a spring-plate, attached'to the table J at its inner end by rivets or screws to and extending beyond the heel end of the former P, and has pivoted to ears on its under side, near its outerend, the connecting-rod ta the lower end of which is fitted to the crank-pin a carried by the shaft w, provided on its other end with the milled wheel V, by means of which the outer end of said plate may be adjusted to a higher or lower level to gage the width of flange to be turned on the stiffener, all as shown in Figs. 5 and 10.

The shaft E and sleeve E may be fitted to gether, so as to be revoluble together, and the shaft movable endwise in said sleevein other ways than that shown-as, for instance, the bore of the sleeve may be cylindrical its entire length, and a short key, gib, 0r pin may be set therein, so as to project into said bore, and the shaft may be cylindrical throughout its length, except that it may have a longitudinal groove or keyway formed therein, into which the key, gib, or pin enters toinsure the rotation of the shaft with said sleeve.

The operation of my invention will be read: ily understood from the foregoing without further description herein.

The notchedflange-turner S will be moved outward by the action of the spring :13, mounted on the rod 00 fixed at one end in a pendent part of the table J, and having a bearing at its other end in an eye 00 set in the arm R, as shown in Fig. 2.
